To all whom it may concern:

Be it known that we, Sir ARTHUR TREvoR DAWSON, knight, and GEORGE THOMAS BUCK HAM, both subjects of the King of Great I Britain, residing at Vickers House, Broadway,.,Westminster, in the countyof London,

7 England, have invented certain new and .use-

1 ful Improvements in or Relating to Gun- .Mountingsmf which the following 1s a spoolthe breech and are carried by a cradle in which the gun recoils on firing.

According to this invention the whole of the sighting apparatus is arranged at the forward part of the gun cradle beneath the trunnions, the sight setter then occupying a position between the carriage cheeks instead of near the breech end of the gun as is customary. The-sight brackets may be pivoted to apart such as the elevating rack moving with the cradle, at a point beneath the forward part of the gun cradle.

''In order that the said invention may be clearly understood and readily carried into effect We will describe the same more fully with reference to the accompanying drawings, in which Figures 1, 2 and 3, are a sectional side elevation, a sectional plan and a sectional rear elevation showing more or less diagrammatically a constructional form of a casemate mounting provided with our improvements. Figsv l and 5 are views similar to Figs. 1

and 3 showing the improvements in conjunction with a modified form of mounting.

A is the gun, B, B are the side cheeks of the carriage and G is the shield. D, D are the sight brackets, D D the gun trunnions and D D the sight carriers. The side cheeks of the carriage are extended downward to about the level of the deck, the distance between the cheeks at the lower part being somewhat greater than at the upper part, and these side cheeks in Figs. 1 to 3 merge into a cylindrical chamber B which passes through a suitable bearing connected to the deck, the chamber being supported in the bearing in an appropriate manner, such as by a number of balls or rollers to facilitate training and having a floor plate 5 The gun is elevated by a hand crank b through a pinion gearing with an elevating rack B arranged centrally beneath the gun cradle and trained by a hand wheel 5".

In the construction shown in Figs. 1 to 3, the sighting apparatus is at the front of the cradle, underneath the trunnions D, D, and the sight setter is seated inside the chamber B a seat 6 being provided for this purpose. This arrangement enables a sighting apparatus of considerably reduced length to be used, and is very advantageous inasmuch that the three numbers who are working the mounting and sights can readily communicate verbally with one another. In this arrangement the sight brackets D, D are pivoted to the elevating racks B", and in consequence the carriage cheeks closely fit the cradle.

In the constructions of mountings shown by Figs. 1 to 5 the mounting is provided with a center plate B to receive the'inner trunnions of the cradles, and theelevating hand wheel bf serves to elevate both guns simultaneously although they can be arranged to be elevated inde endently if desired. The

guns may also separately. I

The arrangement shown by Figs. 4 and 5 is similar to that of Figs. 1 to 3 except that the cylindrical chamber B is dispensed with by raising the mounting sufficiently high to enable the gun layers to be accommodated above the deck; in this case a platform B would be provided on the deck to enable the gun to be loaded. In the construction shown in Figs. 4 and 5 a platform B integral with or connected to the carriage is provided, but this platform may be dispensed with in which event the elevating and training numbers would stand upon the deck within the side cheeks of the carriage and walk on this portion of the deck during the training movements.

e fired simultaneously or What we claim and desire to secure by the sighting apparatus at the front part of the cradle and beneath the level of the gun I trunnions the eye piece of the sight being situated between the" said. side cheeks between which the sighting number is situated. 7

In a gun mounting, the combination Withthe 1 gun carriage having downwardly extending side cheeks between which the sightinganumber i's' situated, the -g'un cradle Gopies 'ot this: Patent may be: obtained to'r 3. In a gun mounting, the combination .With thegun carriage,.the;gun cradle, the elevating rackmovingwith said oradle, and the sighting apparatus, of a sight'bracket forming part of the sighting apparatus and means for pivoting said sight bracket to the elevating rack at a point beneath the level of the gun trunnions.
